I hopefully have a set of LS1 electric fans with wiring that someone had on their 02 chevy truck coming in next week. While I was doing the electric fan upgrade I was thinking about doing the ASP pulley upgrade. I was wondering if anyone is/was having any difficulty with the charging problems. I have a 100 watt bazooka and a 360 watt amp pushing my highs. If you do have both, do you have just the crank pulley or both the crank and alternator pulleys? I have the 5.3 engine.
Any help would be appreciated.

You would probably want to have an alternator pulley to keep the voltage up. During the day, you probably wouldn't notice it, but at night with the lights on, it would pull power pretty hard.

 

yea what richard said. at night with my lights on the alterntator struggles a little bit. but you could just get ls1edit and raise your idle to about 900rpms.

 

GET THE ALT PULLEY. I have one on mine and I'm running about 1500watts <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> My subs alone run on a 1200watt amp. And nighttime was not my friend with the stock alt pulley. The overdrive alt pulley helped, but I still got to much power. In you case, it should fit the bill.

Thanks guys for the info. I emailed Tbyrne motorsports and they said that they will hook me up with the right stuff.

I hear you wont feel a difference with the alt pullie. What is your experience with the alt pullie fast4.8?

 

is there any point in going with pullys if you have an electric fan and dont plan on slowing down the alternator? you would be slowing down the water pump and power stearing, how much is that worth. i am not slaming the pullys but am trying to decide on the best way to get another 1/10 for myself.

 

You will only notice a difference in charging at idle speed. I usually only have a problem while I'm sitting at a red lite at nite with my headlites on HI BEAM and AC on MAX with my 700 watt stero at FULL BLAST and then decide to push the the cig liter to lite up a dobie when I'm reading CHP magazine with my map lite. Other then that it's no big deal. If it bothers you just get the OVERDRIVE pulley or turn in the throttle stop screw on you TB a couple of turns.

 

The pulleys are good. All the camaro's and T/A's have electric fans and the run pulleys. They are worth the money!!!

Horsepower differences is virtually nonexsitant.
